Add benchmarking for Jackson Blackbird

Blackbird will eventually replace Afterburner.

see https://github.com/FasterXML/jackson-modules-base/tree/2.13/blackbird

NOTE: When running this on Java <9, the following warning is logged (incl. a stacktrace).

> com.fasterxml.jackson.module.blackbird.util.ReflectionHack$Java9Up init
> WARNING: Unable to find Java 9+ MethodHandles.privateLookupIn.  Blackbird is not performing optimally!
> java.lang.NoSuchMethodException: no such method: java.lang.invoke.MethodHandles.privateLookupIn(Class,Lookup)Lookup/invokeStatic
